Free online KRA to PNG converter

Source format: KRA

KRA is the native project file format used by Krita, a popular open-source digital painting and illustration application. A KRA file stores the full editable artwork, including layers, masks, blend modes, transparency, brush settings, and sometimes embedded resources such as references or animation data. Artists use KRA files when they want to keep a painting fully editable for later revisions.

KRA is typically used by illustrators, concept artists, comic creators, and digital painters who work in Krita and need to preserve the complete project state rather than a flattened image.

Target format: PNG

PNG is a widely supported raster image format known for lossless compression and transparency support. It is ideal for artwork that needs clean edges, sharp details, and an alpha channel. PNG files are commonly used for web graphics, sharing finished illustrations, archiving rendered images, and importing artwork into other applications.

Compared with KRA, PNG is much more portable because it can be opened by nearly all image viewers and editors. However, it is a flattened image format, so it does not preserve editable layers.

How to convert KRA to PNG

The best tool for this conversion is Krita, since it can open KRA files natively and export them directly to PNG.

1. Open Krita.
2. Choose File → Open and select your .kra file.
3. If needed, check that the artwork looks correct and that all layers are visible as intended.
4. Choose File → Export or File → Export as.
5. Select PNG as the output format and choose a filename such as artwork.png.
6. In the export options, keep transparency enabled if you need a transparent background, and choose the desired color profile or compression settings.
7. Confirm the export to create the PNG file.

If you only need a quick conversion without installing software, you can convert the file on 101convert.com for free.

Quality, compatibility, and limitations

The main limitation of converting KRA to PNG is that PNG is a flattened format. All layers, masks, and other editable project data are lost in the exported image. If you need to keep the artwork editable, retain the original KRA file.

PNG is an excellent choice when you want a final image with lossless quality and optional transparency. For very large paintings, the exported PNG may be sizable, but it will usually preserve visual quality very well. If the KRA file uses special layer effects or blending, make sure the final composite looks correct before exporting, because PNG will capture only the rendered result.
